### Login with Kiwoom API

Source: https://github.com/sharebook-kr/pykiwoom/blob/master/README.md

Demonstrates how to initialize the Kiwoom API wrapper and connect to the service. It uses `CommConnect` to establish a connection, with `block=True` indicating a synchronous operation.

```Python
from pykiwoom.kiwoom import *

kiwoom = Kiwoom()
kiwoom.CommConnect(block=True)
```

### Handle Continuous TR Queries with KiwoomManager

Source: https://github.com/sharebook-kr/pykiwoom/blob/master/README.md

Demonstrates how to perform continuous TR queries using `KiwoomManager`. It shows how to set the 'next' parameter to '2' for subsequent requests after retrieving data, allowing for fetching multiple pages or related data sets.

```Python
from pykiwoom.kiwoom import *

if __name__ == "__main__":
    km = KiwoomManager()

    tr_cmd = {
        'rqname': "opt10081",
        'trcode': 'opt10081',
        'next': '0',
        'screen': '1000',
        'input': {
            "종목코드": "005930",
            "기준일자": "20200424",
            "수정주가구분": "",
        },
        'output': ["일자", "시가", "고가", "저가", "현재가"]
    }

    for i in range(2):
        if i != 0:
            tr_cmd['next'] = '2'
        
        km.put_tr(tr_cmd)
        data = km.get_tr()
        print(data)
```

### KiwoomManager for Subprocess Operations

Source: https://github.com/sharebook-kr/pykiwoom/blob/master/README.md

Explains how to use `KiwoomManager` to run Kiwoom functionalities in a separate subprocess, enabling better separation between the user program and the Kiwoom API client.

```Python
from pykiwoom.kiwoom import *

if __name__ == "__main__":
    km = KiwoomManager()
    km.put_method(("GetMasterCodeName", "005930")) 
    data = km.get_method()
    print(data)
```

### Submit TR Requests via KiwoomManager

Source: https://github.com/sharebook-kr/pykiwoom/blob/master/README.md

Illustrates sending a Transaction Request (TR) to the Kiwoom API using `KiwoomManager`. It defines the TR command with input parameters and expected output fields, then uses `put_tr` to send it and `get_tr` to retrieve the data.

```Python
from pykiwoom.kiwoom import *

if __name__ == "__main__":
    km = KiwoomManager()

    tr_cmd = {
        'rqname': "opt10001",
        'trcode': 'opt10001',
        'next': '0',
        'screen': '1000',
        'input': {
            "종목코드": "005930"
        },
        'output': ['종목코드', '종목명', 'PER', 'PBR']
    }

    km.put_tr(tr_cmd)
    data = km.get_tr()
    print(data)
```
